The statement and the question do not make any kind of sense. Would make more sense to ask who ate more pizza when one ate 2/3 and another one ate 3/4 of an equally sized pizza.
Kid gave a reasonable answer without all the math bullshit

⅔x > ¾y when x > 1⅛y. The question helps you parse word problems.
lechekaflan@lemmy.world 1 day ago
Curriculum and unappetizing methods of teaching are the problems.
This kid has the right to question, to speak out what’s really logical, and is likely to be more street-wise.
FeelzGoodMan420@eviltoast.org 2 days ago
So this was a trick question? Because the student’s answer is correct. That’s the only way it’s possible. Was the answer supposed to be that it’s not possible? I’m a grown adult and I find this question unclear so I’m surprised this was asked to a young child in this way.
Marleyinoc@lemmy.world 2 days ago
Well the teacher’s answer is flat out wrong which doesn’t surprise me at all.

Ahh, fractions and word problems, the bane of my education (seriously, why do we bother with fractions when decimals are easier to compute and express?)
gerryflap@feddit.nl 2 days ago
Imo fractions are way more simple in many cases than decimal numbers. Saying 1/3rd is way more useful than hitting someone with the 0.33333333333333… Quick mental computations with fractions are also simpler in this case. Though this question (and questions like it) seem useless to me indeed.
Anti_Iridium@lemmy.world 2 days ago
I mean I understand, but in the case of .33333333333333… isnt it actually represented as “point three repeating”

who says, 5/6 is easy to mentally understand than 0.83־.

is a reasonable way to start thinking about arithmetics, and basically to start doing simple math IMO.

Man, if you can’t understand fractions, you don’t actually understand the math, you’re just trained to use a formula.
Rooty@lemmy.world 2 days ago
I understand fractions, I simply doubt their utility.
Buddahriffic@lemmy.world 2 days ago
The higher the level of the course I was taking, the less test markers cared about the actual final answer. If you used the correct equations, simplifying the final answer to a faction rather than a decimal or leaving constants like pi and e in there was good enough for full marks.
Generally more accurate, too, because you’re not rounding the number but leaving it as the true value because 1/3 != 0.333333. It’s better to do it this way if there’s multiple steps, too, since you can gather or cancel out like terms if you leave them as variables instead of converting and rounding to some decimal.
jj4211@lemmy.world 2 days ago
People have already commented on fractions, there’s a lot of math that is way easier to keep accurate by leaving in fractional form as it goes.
For word problems, done correctly, the math is pointless if you can’t map it to more realistic scenarios. In terms of applying math to the real world, it’s supremely rare that the world just spits out the equation ready for you to solve, the ability to distill a scenario described by prose to a mathemetical solution is critical. Problem is when they are handled incorrectly and have ambiguous solutions or parameters, but dealing with kids’ homework, this is pretty rare, though it’s admittedly utterly infuriating when it comes up.

I know this is bait but who said they had the same-sized pizzas?
One could be XL the other one a personal pizza.

That’s a base assumption when you compare fractions in these word problems.

reasonableness
Every time this gets reposted, everyone misses this first word.
This isn’t a maths question.
It’s asking the student to read the question and make an observation if it’s a reasonable question and answer.
And with the information provided it’s not.
Korhaka@sopuli.xyz 2 days ago
But it’s perfectly reasonable for Marty to order the bigger pizza because he is a greedy bastard.
chunes@lemmy.world 2 days ago
I’m sorry, what? There is precisely nothing unreasonable about this question. It has a correct answer that can be found with basic logic
Hawk@lemmynsfw.com 2 days ago
Yeah, most pizzerias sell many sizes. Both answers are valid.
In fact, i would argue making an assumption, in this case about size, without declaring it, is in fact less reasonable.

You know we wouldn’t even really need fractions if it wasn’t for your stupid inches and feet right?

This post shows the difference between school and education. The school system is there to get a child to be able to regurgitate whatever the lesson says they should. Education is to develop knowledge as a whole.
It is sad that the teacher was not even able to consider the flawed nature of the question, because they are trained to just see if the student’s answer matches the answer key for the test.
In many cases, the public education system no longer exists to deliver educated graduates. It exists to feed itself – to obtain funding for itself the next year and to support a gradually expanding set of “administrators” that add little to the process.
Look at the effects of “No Child Left Behind”. NCLB pushed test scores above all else. What did we get? A bunch of students that were very good at passing standardized tests. That does not necessarily translate to a better educational outcome. The value in the skill of passing standardized tests plummets rapidly once one joins the workforce.

bluewing@lemm.ee 3 days ago
Boys in particular, (though girls are not exempt from poor handwriting), will have “poor” penmanship pretty much all through elementary school and even into Jr High. And fractions are generally introduced at the end of the 3rd grade school year. And based on the question, that’s the likely grade level that test was created for.
I would bet that most of the students in that class got the answer correct because they were coached to read the question correctly-- to look for the fractions and simply compare them. And anyone else that didn’t, simply chose the wrong answer. Still, you will get a surprise answer like that every once in a while because kids are cool like that. It’s worth a chuckle as you move on.
RememberTheApollo_@lemmy.world 3 days ago
Is there any reason at face value why the teacher’s answer is correct? From my perspective the teacher is an idiot and missing some basic math skills.
infinitesunrise@slrpnk.net 3 days ago
The question literally says “Marty ate more pizza”. It’s a foundational fact that you’re given as a part of the problem. If the answer was the say “Actually, no he didn’t” then you might as well answer “No, he actually at 1/6 of his pizza”.
Artemis_Mystique@lemmy.ml 3 days ago
no way “marty ate more” with the information given.
that is the ‘Expected’ answer

So this is sort of a true/false math problem given to us, the viewer, out of context.

This is likely a question about some topic on reasonable questions and answers, rather than a maths question.

If I saw two people order different sizes of pizzas, my mind wouldn’t be blown, and nobody would consider the situation unreasonable.
remon@ani.social 3 days ago
No. Within the parameters of the question it IS possible and the kid gave the correct answer.
A small fraction of X can have a bigger absolute value then a large fraction of Y when X is suffienctly larger then Y.
Steve@communick.news 2 days ago
I had situations like this at least a few times a year in school.
I usually managed to convince the teacher I was right.And yah this kid is almost certainly ND.
Not just the answer, but the handwriting screams dysgraphia. It looks a lot like mine.jj4211@lemmy.world 2 days ago
Or the kid just understands the given scenario and prioritized coming up with a valid answer instead of assuming the question is bad. You don’t have to be ND to be thoughtful/observant or to be surprised that the question expected to be called out as wrong that early.
On the handwriting, it could be that, or it could be typical elementary school handwriting. Or someone imitating elementary school writing for internet points in a fake math question.

Neither is right: written text is not people, and text without people is either right or wrong until someone read. Only people reading can make the text true, also, you’re a moron.

How is it wrong?
tauren@lemm.ee 3 days ago
It’s a basic assumption in these word problems. For instance, when they ask you to compare 2/4 and 2/8, you know that you can transform 2/4 to 4/8 and see that it’s greater than 2/8. It’s a basic school program, there are no tricks here. It’s a pure math exercise.

I have an argument like that in my calculus 1 class in college, it was an optimization problem but the professor never said that the optimization variable was a constant, so you couldn’t differentiate it to zero and do the normal process that you typically do. So I just wrote that given that the perimeter wasn’t a constant the area to optimize goes to infinite Givin x -> inf; y -> 0, without loss of generality. He marked me zero we discussed about it and I said that I don’t care because I’m going to get a 10 next test if he didn’t fucked up the question. At the next exam I made some stupid error but he still gave 9/10 for the overall class because he came to accept that he wrote the question wrong and I was the only in the class actually caring and giving the class some dedication.
